more explosive force than any of the various kinds so far known.

Another object of my invention is to produce a composition that will prove very cheap to manufacture, one of the reasons therefore being, that I only employ 10% by weight, of the rather expensive element nitroglycerine; the latter may even in some cases be eliminated, as will be hereinafter more fully described.

A further object of my in\ ention has been to provide an explosive composition that will constitute a rather heavy mass, and therefore, be comparatively safe to transport, and proof against mistake, as to its sort or nature, in handling the same.

Another great advantage of my device resides in the fact, that this composition may be handled quite freely, as it will-not explode unless exposed, or made subject, to the 2 application of extremely strong heat, or' rather is acted upon by an electric current of high voltage, applied in the usual manher, that is through the cap-system.

Another feature of my device, rendering the latter of great importance, lies in the fact, that this com osition is substantially smokeless-and free rom odor, thereby making the'said composition especially adaptable to, and useful for, underground work and deep shaft mining, where the retention of clear and pure air is very essential.

It will thus be evident that throughmy said device, I have 'subjugated the objectionable features hitherto inalienably attending 40 the use of, the sort of substances employed at present.

While my invention is capable of being carried out in different ways, further objects of same will appear as the description there of .proceeds.

The said explosive composition is prefer- Application filed September 17, 1927. Serial No. 220,283.

ably made up of the following ingredients 1n the proportions stated:

800 parts ammonium nitrate. 100 parts potassium nitrate. 4 16 parts sulphur.

15- parts manganese dioxide, or peroxide.

6 parts paraflin wax. 6 parts petfoleum naphthaa 15 parts I'OSlIl.

8 parts potato flour.

To this is added 3% aluminum of total weight, and further may be added 10% nitroglycerine of total Weight.

The further process in order to arrive at my said composition of matter is as follows:

The elements of ammonium nitrate and potassium nitrate are firstmixed in the proportions stated; to this mixture are further added, as aforesaid in the proportions stated, sulphur, manganese dioxide (or peroxide), par-afiin wax, petroleum naphtha, rosin. and potato flour; those latter ingredients are then in turn mixed with the former two and stirred well for about one hour. The mass thus produced is thereupon melted to a boiling point and after being cooled off, made into lump-pieces, which are next transformed into a powdered mass in any suitable manner.

To this composition in the present stage is then added 3% of aluminum by weight, obtaining thereby a product which will constitute an explosive composition of a considso erable force, having all the aforesaid properties. It should in this state be specially adaptable for blasting of a less intensive character, for instance, farm work, removing trees, etc.

However, by further adding thereto 10% nitroglycerine by weight, this composition of matter will now, beside the aforesaid properties, possess an explosive force, superior to anything so far known, and, as 90 formerly said, be very safe to handle.

The composition thus produced, when the ingredient of nitro-glycerine in the proportion stated is added thereto, is really considercd by me to be the most important of the compositions disclosed.

It is evident, that modifications may be made in compounding the aforesaid ingredients Well within the scope of thisinvention and the appended 'claims.

Having thus describedimy invention, I claim as new and desire to secure by Letters Patent of the United States:

' 1. A composition of matter for the purpose. described, comprising/ammonium ni trate, potassium nitrate, sulphur, manganese dioxide, paraflin wax, petroleum naphtha, rosin, potato flour, and aluminum.

2. A composition of matter for the purpose described, comprising in combination ammonium nitrate, potassium nitrate, sulphur, manganese peroxide, paraflin wax,

petroleum naphtha, rosin, potato flour, aluminum and nitroglycerine.

3. An explosive composition consisting of the following ingredients: ammonium nitrate, potassium nitrate, sulphur, manganese dioxide, 'parafiin wax, petroleum naphtha, rosin, potato flour, mixed with 3% by weight of aluminum.-

4. An explosive composition consisting of the following ingredients: ammonium nitrate, potassium nitrate, sulphur, manganese peroxide, parafiin' wax, petroleum naphtha, rosin, potato flour, 3% by weight, of aluminum, and 10% by weight, of nitroglycerine.
